USE
measure voltage, current and resistance.
solder the components to a printed circuit board.
cut wire to a particular length.
strip the end of wire, removing the insulation part, leaving
the copper.
hold wire while it is been cut or to hold small components.

SOLDERING
1. Definition
Soldering is a process in which two or more metal items are joined together by melting and
flowing a filler metal (solder) into the joint.
2. Tools
Label the picture →
soldering iron
soldering iron stand
sponge
wire strippers
switch
3. How to solder
a. Complete the SOLDERING GUIDE (the first letter of the word may help you).

IV.
Creating MY FIRST IC
1. Below is a picture of a solderless breadboard ZY-204 with the attached components.
You created this IC during your workshop.
a. Label the picture with the following expressions:
resistor, LED diode, proto board, microchip, switch
b. Draw the diagram of your IC.
↓
2. Below are the diagrams of the first integrated circuit (pic. in Part I) created by Jack Kilby.
a. Label the picture on the left with components and compare Kilby’s IC and diagram to yours.
Use and / but / however.

3. Series circuit or parallel circuit?
Circuits are generally very complex combinations of series and parallel circuits.
Have the components in your circuit been connected in series (along a single path, so the
same current flows through all the components) or in parallel (the same voltage is applied to
each component)?
Answer: ________________________________________________________________
Think of a string of Christmas lights. If any of the bulbs is missing or burned out, no current
will flow and none of the lights will go on. Which circuit has been used – series or parallel?
4. HOMEWORK

Write a short report how you created your IC (tools, components and functioning).
